The Postcode Coordinates file provides an
accurate grid reference for each of the 1.9 million Postcodes in
the UK. The UK currently has over 1.9 million full postcodes (e.g.
UB7 0EB) with each postcode representing on average fifteen sites
Grid references defined by Ordnance Survey's CodePoint locate the
Postcode to 1 meter accuracy of the first building within the Postcode.
As Ordnance Survey only provide data for Great Britain (England, Scotland &
Wales), X&Y Coordinates for Northern Ireland (Postcodes that begin with
postcode area BT) are taken from Royal Mail's PostZon data file. These
PostZon X&Y Coordinates are only accurate to approximately one hundred
meters and are therefore less accurate than the X&Y Coordinates provided by
Ordnance Survey's GB coordinates.
The Postcode Coordinates data is supplied as two separate CSV text files in
order to allow opening and viewing of the data in Excel 2007 which overcomes
earlier record size restrictions.
The Postcode Coordinates supplied in the file will never be more than three
months old and
the file comes with free updates throughout the licence period.
When you order the Postcode Coordinates file you will receive a text based
over 1.9 million UK Postcodes with their appropriate OSGB grid reference
and latitude/ longitude (WGS84) co-ordinates.

The Postcode Coordinates data covers the
United Kingdom (England, Scotland, Wales and Northern Ireland)
The data is supplied as a Comma
Separated Variable (CSV) delimited text file using double quotes by default.
This field format will open very easily using
almost any software application including but not limited to Excel, Word,
Notepad, Access, SQL etc. Due to the size of the file,
older versions of Excel may not be an option as Excel
limits any file size to around 65,000 rows / records.
The Postcode Coordinates data is by default
emailed at the time of order using a secure download link delivery
method. If you require the
data supplied in another format then we will be more than happy to
accommodate you where reasonable to do so at no extra cost.
The Postcode Coordinates list is
licensed annually for each user that has access to it.
The file is updated every three months and free
updates will be made available to you so long as your licence remains
